cmtnfimo DEVICE.

Patented June 9, 19.14.

Application filed October 8, 1813. Serial No. 793,630.

To all wk am it may concern: I

Be it known that I, LEONARD L. FERGUSON, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Cleaning Devices, of which the following is a specifloat-ion.

The objects of this invention are'to provide a manually operative pneumatic sweeper with detachable sweepings and dust receptacles, while the brush is separately dotachable from brush supports on the main body part of the machine. Thus, there is provided a machine of this general type with a sweepings compartment separable from the machine, independently of the brush or any other mechanism liable to interfere with easy dumping of the sweepings compartment.

An illustrative embodiment of this inven-- tion is herewith shown in the accompanying drawings, in which- Figure 1 is aside elevation of a pneumatic sweeper constructed according to this invention. Fig. 2 is a sectional view of the sweeper taken on the line A-A of Fig. 1.

The apparatus to which the present improvements are applied is shown and described in. applicants co-pending applica tion for patent, Serial No. 739,169, filed December 30, 1912. The earlier application shows some features of general construction similar to the present one, the principal exception being that the brus is shown mounted on the detachable sweepings compartment. In the present case the brush is detachable from-the main body part of the machine, but independently of the sweepins compartment.

riefly stated, the ap aratus comprises a main body part 1 in W ich are mounted a plurality of bellows 2 adapted to be successively operated to maintain a continuous suction while the device is in operation.

The bellows 2 are actuated by itman connections 3 with supporting whee s 4, and are adapted to draw air from the article being wheels 10 are journaled in the sweepings.

compartment 7 and are normally in drlving engagement with rubber rollers 11 secured to a brush shaft 12. Secured to the ends of the brush shaft are pins 13 adapted to pass through holes in bearing arms 14.- secured to the base 15 of the body part 1. One or both of the arms 14 are preferably made of spring steel so that the brush may be easily removed. The sweepings compartment is suitably cut away at 17 to permit the same to be moved vertically with respect to the brush shaft 12 which normally rests in said cut away portign as shown in the drawings.

In the operation of the device, the rotation of wheels 10 effects the desired rotation of the brush as in the usual carpet sweeper, the matter swept from the floor being brushed into the sweepings compartment 7. To empty the sweepings compartment the bail 8 is swung upwardly around its pivots so that the said compartment may be removed. When the sweepings compartment is removed, the brush remains on the bracket 14 and therefore does not collect dust or interfere with the emptying of receptacle 7 in a manner possible when the brush is mounted on the latter.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that some of the details of the construction shown may be altered or omitted without departin from the spirit of this invention as define by the following claims.
